GSC Sentinel-2 PDGS SRD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-RD-09-0028 page 90 of 204 S2-PDGS-IDP-115 The PDGS/IDP function shall not propagate potential execution errors and isolate the different processing activities. The execution error of a given processing task shall not impact on others. 5.4.5 DESIGN & DEVELOPMENT REQUIREMENTS S2-PDGS-IDP-120 The PDGS/IDP function design shall allow the simultaneous execution of different instances of the same task or different tasks on the same HW. S2-PDGS-IDP-125 The PDGS/IDP function shall implement the commanding and control mechanisms vis-àvis the DPC function according to a well-defined ICD. S2-PDGS-IDP-130 The PDGS/IDP function design shall be modular with respect to the DPM processingsteps implemented (i.e. each major processing shall be isolated within an independent function allowing easy identification and control of inputs/outputs). S2-PDGS-IDP-135 The PDGS/IDP function design shall derive from a decomposition of the algorithm processing steps into single SW tasks which optimises the parallelisation opportunities of each one when orchestrated within the global processing workflow managed by the DPC function. 5.5 MSI Decompression Software (MDS) Requirements 5.5.1 FUNCTIONAL REQUIREMENTS S2-PDGS-MDS-005 The MDS function shall provide the Sentinel-2 Decompression software with rights to install and use the software (as compiled executable and library API) by ESA or any Third Parties without any restriction of use. S2-PDGS-MDS-010 The MDS function shall provide and maintain an installation and user manual of the Sentinel-2 Decompression software providing software installation and usage guidelines in line with the distributed software.

S2-PDGS-MDS-020 The MDS shall provide the software compiled and validated onto several widely used UNIX-based computer platforms. S2-PDGS-MDS-025 The MDS shall ensure the maintenance of the Sentinel-2 Decompression software alongtime ensuring its validated compatibility and performance with the latest operating system versions while keeping the distribution of older versions running on operating systems deprecated since less than one year. 5.5.2 PERFORMANCE REQUIREMENTS S2-PDGS-MDS-030 The MDS shall provide upgrades of the Sentinel-2 Decompression software validated on new operating system versions no later than 2 months after the public availability of the new operating system version. 5.6 On-Line Quality Control (OLQC) Requirements 5.6.1 FUNCTIONAL REQUIREMENTS S2-PDGS-OLQC-005 The PDGS/OLQC function shall be responsible within the PDGS for systematically verifying whether the generated product data items meet their defined structure, format, and semantics and have general levels of quality and accuracy in line with the quality targets, along the whole mission duration. S2-PDGS-OLQC-010 The PDGS/OLQC function operations shall be performed according to and after triggering by a well-defined processing directive of the DPC function. S2-PDGS-OLQC-015 The PDGS/OLQC function shall make use of the provided data and parameters referred to in the processing directive, including typically: The source PDI to inspect; The configuration of the quality control verifications (e.g. a GIPP); ESA UNCLASSIFIED – For Official Use © ESA The copyright of this document is the property of ESA.
